The KZPBA-CB UltraSCSI host adapter:
•Is a high-performance PCI option connecting the PCI-based host system
to the devices on a 16-bit, ultrawide differential SCSI bus.
•Is a single-channel, ultrawide differential adapter.
•Operates at the following speeds:
–5 MB/sec narrow SCSI at slow speed
–10 MB/sec narrow SCSI at fast speed
–20 MB/sec wide differential SCSI
–40 MB/sec wide differential UltraSCSI
______________________ Note _______________________
Even though the KZPBA-CB is an UltraSCSI device, it has an
HD68 connector.
Use the steps in Table 10–2 to set up a KZPSA-BB or KZPBA-CB host bus
adapter for a TruCluster Server cluster that uses radial connection to a
DWZZH UltraSCSI hub with an HSZ40 or HSZ50 RAID array controller.

to a DWZZH UltraSCSI Hub
Step Action Refer to:
1Ensure that the KZPSA-BB internal termination
resistors, Z1, Z2, Z3, Z4, and Z5 are installed. Section 10.1.4.4,
